Answer

Medical therapy is directed toward lowering IOP, increasing retinal perfusion, and increasing oxygen delivery to hypoxic tissues. The first goal is accomplished by using the same drugs as those used in glaucoma. Retinal perfusion may be increased by administration of vasodilatory drugs although this is unproven, increasing arterial pCO2, or by giving intravascular thrombolytics to remove the offending embolus. Some physicians also advocate aspirin use in the acute phase. Oxygen delivery is improved by breathing higher concentrations of oxygen or with hyperbaric oxygen.
